Who takes advantage of Donald Trump's absence and other things to watch in the Republican debate

Clockwise: Tim Scott, Ron DeSantis, Asa Hutchinson, Nikki Haley, Vivek Ramaswamy, Doug Burgum, Chris Christie, Mike Pence

Eight Republican candidates will meet on the debate stage for the first time Wednesday night in what may be the biggest moment in the GOP’s young 2024 presidential primary so far. The overwhelming front-runner in the contest, former President Donald Trump, won’t participate. He says he’s so far ahead that he’d be helping his opponents by showing up. But his absence also offers them opportunity.

Florida Gov. Ron DeSantis, a distant second to Trump in many polls, is betting that a strong showing will cement his status as the strongest alternative to the former president despite his many stumbles. DeSantis’ team sees rising newcomer Vivek Ramaswamy, a 38-year-old entrepreneur, as a threat, while South Carolina Sen. Tim Scott, former United Nations ambassador Nikki Haley and former Vice President Mike Pence have positioned themselves to compete.

The debate also features a handful of aggressive Trump critics led by former New Jersey Gov. Chris Christie, whose anti-Trump message is the centerpiece of his campaign despite the former president’s continued popularity in the party. Other lesser-known candidates including North Dakota Gov. Doug Burgum and former Arkansas Gov. Asa Hutchinson are largely trying to introduce themselves to voters across the country to help qualify for the second debate.
